Majlis deputies had turned down President Mahmoud Ahmadinejads choices for the ministries of Oil, Education, Cooperatives, and Welfare and Social Security.
Last week, ex-President Hashemi Rafsanjani publicly criticised the executive power for failing to present new substitutes for the rejected candidates.
The most heated debates are expected to focus on Ahmadinejads choice for the Minister of Oil. Irans Oil Ministry is beset by rampant corruption and illegal oil deals by some of the top officials in the ministry.
The new President has vowed to purge the ministry of the mafias that have plundered the countrys oil wealth. Rafsanjanis sons and close relatives are widely suspected of being part of the oil oligarchy.
